Yaa so here`s the answer... since we know that I =mr² i.e MOI depends on r which is distance from the axis.. Initially the water is at a greater distance from the perpendicular bisector or axis. But after rotating the tube it comes near to the axis and it`s distance from the axis decrease. So in the latter case the MI should also decrease..plz approve it if I m right...

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
